Abstract (en)
A door pinch detection device (1), for detecting door pinch when a door (3R, 3L) is driven in a closing direction by a driving force from a motor (11), includes a first obtaining unit (31) for obtaining a first current value indicating current flowing through the motor (11) in a first period while the door (3R, 3L) is closed, a threshold setting unit (32) for, based on the obtained first current value, setting a threshold value used to determine whether the door pinch has occurred, a second obtaining unit (33) for obtaining a second current value indicating current flowing through the motor (11) in a second period following the first period while the door (3R, 3L) is closed, and a determining unit (34) for determining whether the door pinch has occurred based on comparing the obtained second current value against the set threshold value.
